Eunomianism
Classical Protestant confessions receive the Nicene claim that the eternal Son is fully God, while grounding its norm in Scripture and the ecumenical creeds.
Historical context
Eunomius wrote in the aftermath of the Nicene controversy and became a leading representative of an anomoian position, meaning 'unlike in essence.' Basil of Caesarea and Gregory of Nyssa responded to his account of divine knowability and the Son's status. The dispute involved both Trinitarian doctrine and the limits of theological language.
Reception
Classical Protestant confessions receive the Nicene claim that the eternal Son is fully God and that God's revelation cannot be reduced to creaturely categories.
Memory hook
The Son is not unlike the Father as a creature is unlike God.
Key points
- The Son is not a creature whose essence is unlike the Father's.
- The Father's unbegottenness is a personal property, not a higher grade of divinity.
- Divine generation cannot be measured by ordinary creaturely production.
- The question of whether God is comprehensible shapes how theology speaks about revelation and mystery.
Common questions
- Does begottenness imply inferiority?
- Can human language define God's essence?
- How is the Son's relation to the Father different from creaturely origin?
Doctrinal connections
- Trinity
- Divine incomprehensibility
- Begottenness
- Nicene theology
Scripture
- John 10:30 — Christ speaks of unity with the Father; later theology asks how this unity relates to divine nature and personal distinction.
- John 14:9–11 — The Son's revelation of the Father became central to debates about the Son's equality and knowability.
Primary sources
John of Damascus writes:
John of Damascus says that the Father's unbegottenness entails neither a difference of essence nor a difference of dignity in the Son.
all the qualities the Father has are the Son's, save that the Father is unbegotten, and this exception involves no difference in essence nor dignity, but only a different mode of coming into existence.
Passage context and translation
John says that the Father's being unbegotten distinguishes the mode of personal existence without introducing a difference of divine essence or dignity between Father and Son.
